Consider a population of 1024 mutual funds that primarily invest in large companies You have determined that p, the mean one-year total percentage return achieved by all the funds, is 8.50 and that the standard deviation, is 0.75 Complete (a) through (c) GOLD a According to the empirical nule, what percentage of these funds is expected to be within 12 standard deviations of the mean? ☐%

Consider a population of 1024 mutual funds that primarily invest in large companies. You have determined that the mean one-year total percentage return achieved by all the funds, is 7.40 and that o, the H, standard deviation, is 1.00. Complete (a) through (c). a. According to the empirical rule, what percentage of these funds is expected to be within ±2 standard deviations of the mean? 95 % b. According to the Chebyshev rule, what percentage of these funds are expected to be within +7 standard deviations of the mean? 97.96 % (Round to two decimal places as needed.) c. According to the Chebyshev rule, at least 88.89% of these funds are expected to have one-year total returns between what two amounts? Between and (Round to two decimal places as needed.)

Assuming you obtained a random sample of blood glucose levels from 32 individuals from a population and the mean of the population is 120 and the standard deviation of the sample is 15, calculate the probability that the mean blood glucose levels for the sample population will be above 127.

Suppose that an accounting firm does a study to determine the time needed to complete one person's tax forms. It randomly surveys 200 people. The sample mean is 22.3 hours. There is a known population standard deviation of 7.0 hours. The population distribution is assumed to be normal. Find the following. (Enter exact numbers as integers, fractions, or decimals.)
